For a reversible exothermic elementary catalytic reaction of the type A <=K1 ---K2 ->B, what is the optimum operating reaction temperature at a conversion level , xa = 0.8 given- K1 = exp ( 10 -5000/T) K2 = exp ( 40 - 15000 /T) and maximum allowable temperature = T = 300 ok
Discuss the possible individuals and/or organizations that may have been responsible for this injury.
The product is neutralized and washed with water to remove salts. The washed product is usually separated by batch distillation, in which unreacted feeds are recovered first, followed by product, and a polymeric waste is left as residue. The batch..
air at 4mpa and 3000c enters a will insulated turbine operating at steady state with negligible velocity. the air
Determine the 50- Hz applied voltage and the slip at which the motor will develop a torque equal to its 60-Hz full-load value.
A balanced three-phase, wye-connected, 2400- V, 60-Hz source supplies two balanced wye connected loads in parallel. The first draws 15 kVA at 0.8 power factor lagging, and the second needs 20 kW at 0.9 power factor leading.
A spring (not shown in the figure), whose force opposes the magnetic pull, restrains the motion of the armature. If the operating coil has 1800 turns carrying a current of 1 A, and the gaps are set at 0.125 cm each, find the pull that must be exer..
The star point on the primary side of the transformer bank is grounded. The load consists of a heating load of 2 kW per phase and a three-phase induction-motor load of 20 kVA with a lagging power factor of 0.8, supplied at 230 V line-to-line.
Styrene can be made by catalytic dehydrogenation of ethyl benzene. The reaction is usually carried out in the presence of steam, which acts as a heat carrier and reduces coking on the catalyst.
A storage tank is purged continuously with a stream of nitrogen. The purge stream leaving the tank is saturated with the product stored in the tank.
question 1the effect of a hazardous substance depends on the concentration of the substance that is present in the
For a slip of 2.00%, compute the speed, output torque and power, stator current, power factor, and efficiency when the motor is operated at rated voltage and frequency. Neglect the impedance of the source.
A beaker filled with an equimolar liquid mixture of ethyl alcohol and ethyl acetate evaporates at O°C into still air at 101 kPa (1 atm) total pressure. Assuming Raoult's law applies, what will be the composition of the liquid remaining when half t..
